Celemantia Roman Fort (Iža-Leányvár)

Celemantia (or Kelemantia; the modern name of the site is Leányvár) was a Roman castellum and settlement on the territory of the present-day municipality Iža (Hun: Izsa), some 4 km to the east of Komárno in Slovakia. It is the biggest known Roman castellum in present-day Slovakia. It was a part of the Roman limes, the frontier-zone of the Empire.
A Germanic settlement "Celemantia" in this area is mentioned by Claudius Ptolemaios in the 2nd century AD. It can be identical with the remnants of a civil settlement found next to the castellum or with another unknown settlement or, as some historians assume, it is the name of both the castellum and the remnants of the civil settlement.
The construction of the castellum started in the 2nd half of the 1st century. It was conquered during the Marcomannic Wars (166-180) and burned down by Germanic tribes, and was rebuilt later. It ceased to exist around 400 (beginning of the Migration Period). The ruins were very well visible up to the late 18th century, but afterwards people used stones from the constructions to build the fortress and other buildings in Komárno.
According to a local legend, a Roman soldier, Valentin, kept his mistresses in the fortress. The fictitious story explains the origin of the name Leányvár, meaning Girl Castle in Hungarian. However the name probably refers to the fact that the ruins of the castle were donated by King Béla IV of Hungary to the Dominican nuns of Margitsziget who later built a small fortress among them. en.wikipedia.org/wiki/Celemantia

The Iža-Leányvár Castle (Latin name Celamantia or Kelamantia) was a Roman military camp on the territory of today's Slovakia, Nitriansky District, Komarno County. It served to secure an important river crossing and bridgehead on the north bank of the Danube, the latter being directly opposite the legionary camp of Brigetio. In large sections, the river formed the border (Limes Pannonicus) of the Roman province of Pannonia Superior to the so-called Barbaricum, so that the crew of the fort also carried out security and surveillance tasks in this section.The fort is the largest known Roman military settlement in Slovakia. Its remains, which are open to the public, are located on the eastern outskirts of the southern Slovakian village of Iža, in the immediate vicinity of the banks of the Danube. However, due to a lack of modern excavations, many structural findings that were discovered shortly after the turn of the 20th century cannot be clearly assigned to a specific time. The fort site has been part of the Danube Limes, which has been declared a UNESCO World Heritage Site (Wikipedia), since 2021.
